Warning signs, we see them every day as we drive, and if you drive enough you may barely even notice them. However, they require your undivided attention to keep you and your fellow travelers, pedestrians, and road workers safe.
Chainzone supply professional and honest service.
It's important to be able to immediately understand the information posted on placards along streets or highways, so the United States Department of Transportation Federal Highway Administration (FHWA) has set standards for both the color and shape of signs to ensure conformity. Additionally, many signs contain only symbols, providing instant communication in any language.
The color of road indicators signifies what type of information they contain. For example, warning signs have a yellow background with black lettering or symbols. The shape of a placard also conveys information. Most warning signs have a diamond shape for easy and quick recognition. However, there are exceptions, such as the rectangular sharp bend in the road indicator and the pennant-shaped No Passing Zone placard.
The importance of warning signs cannot be overstated. They are strategically placed for your protection as well as the protection of others, warning drivers of approaching conditions that may be dangerous. They are there for a reason and are therefore important to heed.
Here are 10 of the most common warning signs you are likely to see on the road:
This indicator is diamond in shape, with the symbol of a car skidding to indicate the particularly slippery conditions of the pavement up ahead. The danger may be due to rain or ice, and drivers are warned to slow down appropriately. Be careful not to turn or change lanes suddenly, or brake too hard. You should slow down for turns, and increase the distance between your car and the one ahead.
The Traffic Signal Ahead placard is another diamond-shaped sign with a 3-color traffic light depicted on it. When you see this, you should know to stay alert and be ready to slow down, anticipating the intersection and the possibility of a yellow or red light ahead.
The Stop Ahead placard is warning you to slow down in anticipation of a full stop coming up. You'll need to come to a complete stop before proceeding cautiously. This is also diamond-shaped.
A Left Turn Ahead placard warns you that the upcoming stretch of roadway curves to the left, so slow down and stay to the right. The same cautions apply with the Right Turn Ahead, only now you will want to stay to the left side of the street as you carefully approach the turn.
This indicator is rectangular with a black arrow pointing in the direction of the curve. It indicates the road ahead is changing directions at an extreme angle, so you need to slow down considerably before you reach the curve.
The Merging Traffic indicator will show you the direction the new traffic is coming from, usually from the right but not always. Be ready to either change lanes or to allow the oncoming traffic to safely merge into your lane. Merge placards often appear on expressways just before ramps, to allow safe entry onto the expressway. Drivers entering from the right must yield to traffic on the main route but be careful, not all drivers obey this rule.
You're driving at highway speeds, about to exit the highway, when you see the square or rectangular, orange and black 'Exit Ramp' speed placard. You may be in a hurry and therefore fail to slow down enough to safely navigate the ramp, which is usually in the form of a curve, sometimes a steep curve. This placard advises you of what the safe speed is as you are exiting the highway, based on many factors.
Also, keep in mind that bad weather and poor conditions will determine a truly safe speed, which may be less than what is posted on it.
Another pennant-shaped, yellow and black indicator that indicates you've entered a stretch of highway or road where passing is illegal or unsafe. The indicator is on the left side of the street, facing the driver, so if you have already started passing, you must complete it before entering the No Passing Zone.
This is often placed at the base of a hill or before a curve, places where you cannot see far enough ahead to pass safely. This is usually accompanied by a solid yellow lane-marking on your side of the road.
The shape of this sign is unique; it is five-sided with black on yellow lettering, and is only used to warn of schools and school crossings. You must slow down, school zones have a posted speed limit that you must observe. Children may not always be careful so it is your responsibility to watch out for them. They may be playing or crossing the street, so you must be prepared to stop. There may be crossing guards present or school buses nearby as well.
You may also see the newer yellow-green placards instead of the usual black and yellow indicators in the same shape. These have improved visibility, providing a greater chance of child safety.
A deer crossing indicator indicates that deer are frequently in the area, so you should be sure to slow down and be on the lookout for them, especially at dusk. Not only can you injure or kill one, but they can do a lot of damage to your car, and possibly even injure you or your passengers.
Warning signs are present to alert you that there is a change coming of which you need to be aware. These placards are posted to protect you as well as other motorists, road workers, and pedestrians.

Variable Message Signs (VMS) are commonly used on roads, highways, freeways, motorways, tunnel entrances, and in rural areas throughout Australia. VMS are extremely beneficial for increasing road safety performance because they can directly signal to a motorist on the road, many types of information quickly and effectively.
It's more than likely that you would have driven past at least one of these electronic traffic signs or seen one as a passenger on your travels ' can you recall the last time you saw one?

Perhaps you were stuck in a traffic jam on the way home from work, getting frustrated as to why there was more traffic than normal. You ask yourself, what's going on up ahead? All of a sudden, you can see an electronic traffic sign explaining that there has been a traffic incident up ahead, along with an expected timeframe for the additional delay in travel time.
Providing this type of information to motorists via a Variable Message Sign benefits the motorist by relaying information on why there is a delay using a few short phrases or words. This is just one familiar situation to all of us that might help you to begin to see the benefits of using one or more VMS in different road scenarios.
Let's look at some additional benefits of having a Variable Message Sign for improved road safety. They increase road safety by communicating important traffic information directly to motorists. Below we have compiled a list of the 3 key benefits of using these important road safety tools.
3 Key Benefits of using a Variable Message Sign
Traffic congestion is an ongoing transportation problem that motorists and road authorities encounter daily. The level of traffic congestion can rapidly increase with travel growth, roadway expansions, and developing infrastructure projects. These 3 main factors among many others can interrupt the desired capacity of motorists that can travel on roads, causing a significant amount of congestion. Although this work is paramount to growing communities this can be disrupting to motorist usual travel times, increasing driver frustration.
As a result, the congestion can cause further delays, uncertainty in travel time and increase accident rates. So, how can we use a Variable Message Sign to help reduce congestion?
When deploying a VMS, it's worth considering the unexpected situations, like traffic incidents and emergencies, that occur daily on the road and cause congestion. Having a VMS in these situations can provide advanced warnings directly to road users to help them stay informed and make an alternate choice, wherever possible.
In addition, setting up a VMS prior to planned road works beginning can provide notifications to motorists of future events, that may impact their journey. Providing this information well in advance can help a driver determine an alternative route, or even allow for more time to get to their destination thus reducing traffic congestion.
In Australia, according to the National Road Safety Strategy the number of lives lost due to road related incidents are, on average, each year. Changing road conditions can provide an unexpected situation for motorists, particularly those that are used to travelling the same route each day on a familiar road. Using a Variable Message Sign to display advanced warnings to motorists, can help to prepare themselves for a change and could mean the difference between someone returning home safely or an unfortunate accident.
When placed correctly Variable Message Signs can really help reduce the likelihood of crashes. More specifically rear-ended crashes. These accidents occur when traffic comes to a sudden, unexpected stop. Below are 2 examples where VMS can be used to help prevent accidents.
Example A ' Lane Closure Advanced Warning
A VMS can be set up to provide advanced warning of an upcoming lane closure. The VMS informs the driver of a changing traffic condition they are about to enter. Alerting drivers of an upcoming lane closure prior to the actual closure, ensures the driver can make a decision and take the necessary action ahead of time.
Without VMS communication the driver could be left in shock by the road closure, which could result in last minute braking or worse, a collision.
Example B ' Speed Limit Changes
Speed limit changes and alterations need to be communicated to all motorists. A Variable Message Sign can be used to provide a range of different speed limit change messages, including the display of an actual speed limit sign, as seen in the image below. This provides information to the motorist advising alterations on speed limit or the reason for a speed limit reduction.
Both Permanent and Portable Variable Message Signs can display a range of messages, across one or more screens. This allows ability to communicate quickly and effectively with motorists.
In addition to displaying multiple messages, VMS can operate in conjunction with a range of accessories to provide further detailed traffic information, including:
Real-time traffic information relating to road incidents
Live estimated travel times
Detect and advise speed limits
Having additional information for communication to motorists and the ability to delve deeper into data that can be analysed for many purposes. If you are interested in learning more about detailed traffic information, head over to our VMS product page to view the range of accessories that can enhance the capabilities of Mobile Variable Message Signs.
Fixed vs. Portable Variable Message Signs
There are two main types of VMS, Permanent and Portable VMS. Both types of VMS come in a range of sizes for different applications. Fixed and Mobile Variable Message Signs have many similarities including dynamic messaging, remote programming, numerous communication options, and bright multi colour displays.
However, the use and application of each type are different. As the name suggests Permanent VMS are often mounted on highway bridges and tunnel entrances in a place that they will remain long term.
Alternatively, Mobile Variable Message Signs are trailer mounted for easy mobility. They can be easily moved from one location to another, for both short- or long-term usage.
Permanent/ Fixed Variable Message Signs
Permanent or Fixed VMS can be found in many different sizes, depending on the application, primarily in a large rectangle shape. They are designed to effectively deliver traffic information to motorists. Such as information reporting traffic congestion, temperature, lane controls, speed limits, and changes in usual traffic conditions.
Occasionally known as Variable Message Signs Tunnel, as they are often equipped to tunnel entrances to display travel time and tunnel lane closures.
Permanent VMS are often used on highways, roadways and tunnel entrances.
Mobile/Portable Variable Message Signs
Mobile Variable Message Signs have become a staple part in traffic management and community awareness projects, as they have been shown to effectively disperse traffic away from work sites, potential bottlenecks or known problem areas. Mobile VMS can be used for several different reasons including traffic management, roadworks, advertising, and events.
For traffic management application portable VMS can be used to advise road/lane closures, communicate with a motorist and local traffic of any changes usual traffic conditions, providing directional information, displaying safety information, accident management and speed related messages.
The below images are slides from a portable variable message sign advising a road closure ahead.
